A perhaps even larger problem is that Twitter dumps all tweets on all topics from everyone into that network. You can't follow someone to learn from them in their area of expertise without also hearing their political opinions, religious biases, and such. That injects conflict even though none exists naturally.
I don't know if Mastodon is the answer, but the ability to separate your posts by type would be a massive improvement. The ability to post on different servers makes it possible.
The strength and weakness of Twitter was dumping "everyone" into a very flat network. Increasingly that just sets people at war with each other.
